Why the search exists
Copies on other suffixes go dark, and the people who bookmarked one go looking for the next. You are on the site the copies copied: search by title or actor, the shelves, every season of every series, My List, and Watch now for your country.
What to compare
Four things decide whether a movie site is worth keeping: how deep the catalogue goes, how fast search finds a title, whether series are organised by season and episode, and whether it works on a phone. Here the catalogue runs from this year's releases through the franchises and the 2000s classics to a Vietnamese shelf; search is instant; every series has a page per season with the episodes dated; and the app installs in two taps. The lists elsewhere recycle the same dozen names, most of them copies of one another; bookmark the real address instead.
The better alternative
For a title you will watch three times, the service you already pay for is the right place, and the Watch now list on every title names exactly those services, with the price where there is one. That is a more useful alternative than another clone, because it is where the film plays in HD with subtitles and downloads in the service's own app.
